Abstract Understanding macro controlling factors is necessary for evaluating actual soil and water loss and predicting future trend. Based on the geological background of Guizhou Province, the relationship between the geological conditions and actual soil and water loss and its potential danger was studied. The results indicate that the geological condition is one of the most important factors affecting regional soil and water loss, which determintes the space distribution of soil and water loss's potential dangerous degree. At the same time, the whole province is divided into 6 sub-areas of soil and water loss and their potential trends are evaluated and described.
